She said: “I’m over the moon to be joining the show, it’s such a huge part of British telly.

“I’m really looking forward to getting started and I can’t wait to see the Square in the flesh. Walford here I come!”

Although it’s her pop career that made Hannah a household name, she is already an established actress, with past roles in ‘Primeval’, ‘Death In Paradise’ and ‘Casualty’ (not to mention the oft-forgotten S Club film, ‘Seeing Double’).

Tamzin’s soap comeback, and Hannah’s impending arrival, are among the first moves from John Yorke, who is temporarily serving as executive producer of ‘EastEnders’ following the sudden departure of Sean O’Connor over the summer.
